[QUOTE=snowflakeuniverse;1112511]Hi hha1

A bit of both. I live in the hills above Los Angeles. Visual magnitude in my backyard from NW to NE was +3.5, which is as good as it gets. I barely can see the comet, but with the 60 second exposure the faintest stars visible are about +9.5.

If you see fog in your picture you probably have set the iso too high.

Set gamma=2 or change levels to 2 to 50 in PhotoShop. Need to experiment.

>Out of curiosity, have you had any problems with the LZ3?

No problems this far. The 6-36 mm f/2.8-4.5 lens is very good. The 1/2.5" 5 Mp CCD is relatively better than some of the newer CCDs which squeeze 10 Mp into the same size CCD.

It sounds like you have an LZ5 (6 Mp with the Venus II engine, otherwise very similar to the LZ3) and an FZ50.

Never had a problem with any of them. My Olympus D490z (3z zoom, 2 Mp)
still works, produces good pictures, but is ever so slow.

The LZ3 in Stary Sky mode uses iso80 only. In non-scene modes the iso is selectable from Auto, 80, 100, 200 and 400. I keep it at iso100.
